Class UISwapContainer

Method Details

• getPredefinedProps

  public void getPredefinedProps()

  Gets potential references to predefined properties for this container. This method is called once just after cloning of the property container.

  The method should get reference to using the getProp(...) methods. This allows the subclass to be able to retrieve the new instances to the properties created during addPredefinedProps() if stored in instance variables.

  Subclasses must override this method to do the appropriate initialization, as this method does nothing for the PropCnr class implementation.

  Overrides:

  getPredefinedProps in class UIContainer

• clone

  public UISwapContainer clone()

  Creates a clone out of this property. The cloning is overridden by the subclasses in order to handle cloning of its class variables appropriately.

  Cloning is used for "virtualization" of a property tree in the server. Client property classes will therefore throw CloneNotSupportedException.

  Once a tree has been cloned, the change-flag is reset, and the create-flag is set. All listeners are also removed! The new cloned property is an orphan, i.e. has no parent set. All children properties are also (deep) cloned.

  Note that the cloning process is done WITHOUT thread synchronization for performance reasons, thus no modifications should be done to the tree!

  Overrides:

  clone in class UIContainer

  public boolean mustHaveWidth()

  Does this component require a width?

  Overrides:

  mustHaveWidth in class UIContainer

  public boolean mustHaveHeight()

  Does this component require a height?

  Overrides:

  mustHaveHeight in class UIContainer

  Returns:

  true if the height must be defined and non-zero, false otherwise.

• mustHaveExplicitWidth

  public boolean mustHaveExplicitWidth()

  Does this component require an explicitly defined width?

  Overrides:

  mustHaveExplicitWidth in class UIComp

  A value indicating the selection capability as the SELECTION_TYPE_* values define.

• getSelectedIndex

  public int getSelectedIndex()

  Gets the first selected index.

  Specified by:

  getSelectedIndex in interface IUISingleIndexedSelectionComp

  Returns:

  The first index in the current selection, or -1 for none.

• isAnimated

  public boolean isAnimated()

  Returns the animation flag.

  Specified by:

  isAnimated in interface IUIAnimatedSingleIndexedSelectionComp

• isSelected

  public boolean isSelected()

  Returns the selection of state of the component.

  For a multiple-selection capable component, this indicates any selection, i.e. true is returned as soon as at least one element is selected, false for none.

  Parameters:

  cr - The class reference with a valid reference.

  errors - The list of errors that is returned to the caller in case resolving fails.

• getOnUISelectionMethod

  public Method getOnUISelectionMethod()
